The cover plate is detachably connected to the bottom shell and seals the opening, which is convenient for opening the cover plate to overhaul and maintain the electrical equipment and protects the electrical equipment in the accommodating cavity.

[0009] Preferably, an inner wall of the bottom shell is formed with a step extending along a width direction of the support frame, the step is arranged on a side of the bottom shell close to the transmission mechanism, and the step is used for avoiding the transmission mechanism below.

[0010] In the present scheme, by arranging the step on the bottom shell, the electric control box shell can avoid the transmission mechanism below and be installed on the support frame, and the volume of the electric control box shell can be made smaller, so that the electric control box shell is more closely connected with the support frame, space is further compressed, and the stacking effect is improved.
